dc.abstract.en There is suggestion that trait anxiety influences the processing of threat-related information. To test this hypothesis we recorded ERPs in response to subliminally presented and backward masked fearful and neutral faces, and non-face objects, in the preselected low- and high-anxious individuals. The amplitude of N170 was found to be larger when elicited by faces in comparison to non-faces, however it was not found to be emotion-sensitive or modulated by anxiety level. Differences between low- and high-anxious individuals appeared in a time window of the P1 component. At later stages, within the EPN component, stronger negativity specific for fearful faces was recorded exclusively in the low-anxious participants. Our findings indicate that anxiety level modulates early stages of information processing, as reflected in the P1 component. This leads to anxiety-related differences in involuntary emotional expression detection at later stages (EPN component). pl
